Rare Celestial Event: Betelgeuse to Temporarily Vanish in Unprecedented Eclipse

Betelgeuse, one of the brightest stars in the sky, will briefly disappear as an asteroid called Leona blocks its view over a thin strip of Earth's surface on December 11. This rare celestial alignment is being hailed as a once-in-a-lifetime event that will allow scientists to observe Betelgeuse's ever-changing surface in the best resolution to date. Occultations of bright stars like Betelgeuse are extremely rare, occurring less than once a century.
